Revert "arm64: dts: qcom: Fix 'reg-names' for sdhci nodes"

This reverts commit afcbe252.

The commit in question caused my sc7280-herobrine-herobrine-r1 board
not to boot anymore. This shouldn't be too surprising since the driver
is relying on the name "cqhci".

The issue seems to be that someone decided to change the names of
things when the binding moved from .txt to .yaml. We should go back to
the names that the bindings have historically specified.

For some history, see commit d3392339 ("mmc: cqhci: Update cqhci
memory ioresource name") and commit d79100c9 ("dt-bindings: mmc:
sdhci-msm: Add CQE reg map").
